    Question SATA3 drive on SATA2 motherboard

    Now obviously I can do this but... are there any downsides apart from not being as fast as it could be?

    Drives in question are Seagate Barracuda 2TB Green and Sandisk Extreme 240GB SSD



    Thanks

    Re: SATA3 drive on SATA2 motherboard

    I doubt it'll make any difference to the Seagate drive at all.

    The Sandisk drive will be bottlenecked, particularly in sequential reads/writes, but other than that I don't think it makes any difference at all.

    You could always pair it with something like one of these:

    If you wanted full bandwidth.

    Thanks

    I have no spare slots on my motherboard, I think it might be time for an upgrade.

    Re: SATA3 drive on SATA2 motherboard

    Hi TechieBloke

    Just installed a couple of OCZ Agility 3 120gb Drives, for myself and some friends, and while I have SATA3, their SATA2 controllers keep up extremely well in normal tasks such as loading applications and Battlefield 3 levels. In fact without benchmark numbers, I would be hard pressed to tell the difference.

    There is the possibility I need to further tweak my setup, so I am looking into that now.

    Just to add, one of the ssd's is on a separate sata2 controller, the other sharing with the existing hdd.

    Re: SATA3 drive on SATA2 motherboard

    The bottle neck will be small and not really that noticeable
    I put a curcial M4 in a shuttle with an H61 motherboard, that only has sata2 and it's still plenty fast, windows7 boots to desktop in under a minute.

    as to the hard drive that's not going to be anywhere near maxing out sata2, you could drop it right down to sata1 and it would only be very slightly bottlenecked

    Re: SATA3 drive on SATA2 motherboard

    What is the bandwidth limits of SATA2? I'm thinking about putting an SSD in my old(ish) system and wondered whether it was worth a SATA3 card or not.

    Re: SATA3 drive on SATA2 motherboard

    Sata 2 runs at 3 Gbps (giga bits per second) which is still very quick
    Sata 3 runs at 6 Gbps

    Sata 3 cards can be got for not much more than a tenner so possibly worth it, check any issues booting from them first
